"Will there be more content coming for BG3?" We know what we are doing next, and we can't talk about it but probably not any additional content for BG3.
I would say this is a good thing actually.
In my experience, the only companies that starts working on DLC/Expansion imediately after they release the game, are companies that cut that DLC/Expansion out of original story.
I say let them work on something else next ... And we will see what opourtunity future brings.
I still dont understand why cant we change Race for our hirelings. Lets us play Githyanki as racist as they trully are!
